Fencer: But I hope you are not also tired of fixing the bugs (though one may think so because some are open for many years now).

Some bugs still open:

Camelot: sometimes the server lets a player make a canter with a knight while a capture is possible. This seems to happen only when the moved knight could make a knight's charge.

Grasshopper: if both players are blocked, the game should be ended by the server. See for example game 5235400.

Espionage: the server sometimes accepts a move where a piece moves to a square it just came from in the previous turn. Seems to happen only if the moving player has fewer pieces to move than one should move in a turn. (BTW I find it desirable and more logical to apply the spying after the removing of the pieces captured in that turn, i.e. pieces captured in that turn do not reveal and are not revealed).

Fevga: the server should force a player to unblock the opponent if the latter would otherwise not be able to move any dice-roll. And the coordinates at the board do not match those in the moves list.

Crowded Backgammon (maybe also other variants where there are initially pieces on the bar): if the loser has not born off any stone and still has stones on the bar that have been there from the beginning, the server (sometimes?) doesn't count the game triple. (however, the rules don't state explicitely how this case should be handled).
